 ## Steps
-### 0. Installing the 'fedora-33-minimal' Qubes template
 
-Note: an alternative is using an fedora-{33,34} appVM.
-
-#### Open a terminal in Dom0
-
-Large download (~639MB); if using 'sys-whonix' as the Dom0 UpdateVM then temporarily swap to 'sys-firewall' (to speed-up download speeds).
-```console
-# qubes-dom0-update qubes-template-fedora-33-minimal
-```
-Keep in mind what Qubes OS version your installation is; used when building Qubes Components and Template(s).
-```console
-# cat /etc/qubes-release
-```
-```
-# qvm-run -u root fedora-33-minimal xterm
-# dnf install qubes-core-agent-passwordless-root qubes-core-agent-networking iproute
-# exit
-```

 `$ strings /usr/bin/make | grep MAKEFLAGS` \
 GNU Make's `-l` set to same value as `-j` prevents CPU overcommitment.**

-The partition used for the build process needs the suid option, in the qubes-builder remount script.
-In the `/home/user/qubes-builder/scripts/remount` file change the line:
-```
-sudo mount "$mountpoint" -o dev,remount
-```
-with:
-```
-sudo mount "$mountpoint" -o dev,suid,remount
+During the template building process an error ocurred, corrupting the group id of the /dev/xen/* files.
+To fix this you'll need to assign the correct permissions, so you'll have to enter the following <b> while `make template` is running:
+```console
+sudo chgrp qubes /dev/xen/*
 ```

 ## Debugging the Qubes-ArchLinux runtime
 If you are able to launch a terminal and execute command, utilize your Arch-fu to fix the issue. \
 If unable to launch a terminal, shutdown the qube, create a new DisposableVM, [mount an Arch Linux ISO in a DisposableVM](https://www.qubes-os.org/doc/mount-lvm-image/), chroot to it, and then use your Arch-fu. \
